Sven Jantzon uses Lucas Transmission Fix in 1977 Ford Maverick 302

I have previously submitted a testimonial regarding your Heavy Duty Oil Stabilizer. I felt it was necessary to inform you that I am even more-so inclined to use your products.

Just the other day, I poured a bottle's worth of Transmission Fix into my original C4 transmission, which recently began to slip [hence the fact this car is my daily-driver.] I ran the car for a few minutes, exercising all the gears, leaving it to sit overnight. The next morning I took it out for a drive and - in all honesty - noticed I was actually getting into second gear without slipping. To this day all the gears work as if nearly new without hesitation; also smoother shifting.

Thank-you Lucas Oil for your irrefutable products.
